SEWER-TRAP.

SPECIFICATION forming part of Letters Patent No. 405,774, dated June 25, 1889.

Application iled January 29, 1889. Serial No. 297,964. (No model.)

Ldo all whom it may concern:

Be it known that I, GEORGE C. HAGER, a citizen of the United States, residing at Danbury, in the county of Fairfield and State of Connecticut, have invented anew and useful Improvement in Sewer-Traps, of which the following is a specification.

My invention relates to an improvement in sewer-traps; and it consists in the peculiar construction and novel combination of devices, that will be more fully set forth hereinafter, and particularly pointed out in the claim.

In the accompanying drawings, Figure l is a vertical sectional View of a sewer-trap embodying my improvement, showing the stopper or valve closed. Fig. 2 is a similar view showing the stopperor valve open.

A represents a sink, which is provided with an outlet-opening B, having a depending side flange C, and over the said opening B is arranged a strainer-plate D, the latter being countersunk in the bottom of the sink.

E represents the lead pipe, which is provided at its upper end with a flared flange F, adapted to engage the depending flange C and to effect a tight joint therewith. A flared collar Gis slipped over the leadl pipe and engages the flared upper end F thereof, and bolts H extend through openings in the bottom of the sink and through openings in the collar G, and serve to clamp the latter against the flange F and to press the said flange against the flanged portion C of the sink. The lower end of the lead pipe E is curved, as at I, and the said lead pipe is provided at a suitable distance from its lower end with an inverted conical valve-seat or an annular offset K. Cast integrally or otherwise formed on one side of the lead pipe is a chamber L, which is provided with a vertical central partition M, the latter extending nearly to the upper end of said chamber. Channels N O are thereby formed in the said chamber, the same communicating with each other at the upper end of the chamber, the said channel N communicating with the lead pipe below the valve-seat K and the channel O communicating with the lead pipe above the said valve-seat. In the upper end of the chamber is a threaded opening P, which is normally closed by a screw-plug R.

S represents a plunger-rod, which extends downward in the lead pipe and passes through an opening' in the center of the strainer-plate D. To the lower end of the said plunger-rod is secured a valve T, the same comprising a pair of inverted conical plugs U and a rubber disk V, which is clamped between them. The said plugs and disk are adapted to fit snugly in the valve-seat, and thereby effectuallycut off comlnunication between the lower ends of the channels N O. To the upper end of the plunger-rod S is pivotally jointed an extension \V, the same having a button X at its upper end. The length of the plunger-rod and of its extension is such that when the valve is firmly secured in the valve-seat the button X is bearing on the upper side of the strainer-plate, as shown in Fig. l. Vhen thus arranged, waste water from the sink must first descend through the upper portion of the lead pipe, and then ascend in the channel O until it overflows the partition M, so it can escape through the channel N into the lower portion of the lead pipe, and from thence into the sewer. Consequently a water seal, as indicated in Fig. l, will be formed in the lower end of the channel O and in the upper portion of the lead pipe above the valve when the latter is closed, and therefore the sewergas will be entirely excluded and cannot possibly escape into the building.

By grasping the button X the rod S maybe withdrawn, so as to raise the valve U, and thereby establish communication directly between the upper and lower part of the lead pipe and prevent water from accumulatingin the chamber L, and thereby avoid the danger of freezing the trap in cold weather.

By withdrawing the extension NV of the plunger-rod its full length and laying the same in a horizontal position in the bottom of the sink by bending it at right angles to the said rod S, as shown in Fig. 2, the valve will be supported in its elevated position.

Having thus described my invention, I claim- The combination, with a sink, of an escapepipe having a chamber formed on one side thereof with its upper end below the level of the sink, a vertical partition in said chamber terminating at a distance from the upper end of the latter, openings connecting the lower IOO ends of the compartments 0f said easing' with the Said pipe, a valve seated in the Iatter between the said. openings, and a jointed oper-- ating-rod extending from said Valve upwardly through the strainer-plate of the sink, substantially as and for the purpose herein set forth. i

In testimony that I claim the foregoing as my own I have hereto afxed my signature in presence of Vtwo witnesses.
